**What happened:** Microsoft announced the Surface Laptop Ultra and the Surface RTX Spark Dev Box on 7 October 2026. Both use Nvidia's RTX Spark technology, according to [Tech Startups](https://techstartups.com/2026/10/08/top-tech-news-today-october-8-2026-globalfoundries-google-manus-microsoft-nvidia-openai-tencent-more/).

**The numbers:** Surface Laptop Ultra starts at $2,600. A stronger configuration starts at $3,700, and top versions reach $5,900. The RTX Spark Dev Box starts at $6,000.

**The details:** Microsoft says the laptop supports up to 128GB of unified memory. It can run models with more than 120 billion parameters locally.

**Why it matters:** Both machines are built to run large AI models on the device itself rather than elsewhere.

**Who's affected:** Organisations get a new tool alongside the hardware. Microsoft Execution Containers (MXC) is now generally available on Windows 11. It lets organisations run AI agents in controlled environments.

**In their words:** Microsoft said of those controls: "Those restrictions are enforced while an agent operates."

**What's next:** Microsoft expects more Copilot features over the coming months. They will use local context and act on users' behalf.

## Key takeaways

- Surface Laptop Ultra starts at $2,600
- Laptop supports 128GB memory and 120B+ parameter models
- MXC for AI agents is now generally available
